Malwarebytes Anti-malware Premium is the best antivirus in my personal experience, I am using this since 2015 and now it is 2018. I have used almost all the antivirus software and concluded that Windows Defender (you need to activate your Windows to use updated Windows Defender – Activate Windows Here) and Malwarebytes Anti-malware Premium Full Version.
Malwarebytes is currently running awesome and it is considered as the future’s best antivirus as well. It detect or block millions of known and unknown threats every day. This invaluable threat data gives us incredible insight into what’s happening now, in real-time. But even more importantly, that intel combined with our artificial intelligence (AI) technology anticipates future threats. So you’re not only protected from today’s threats, but tomorrow’s as well.
